A method and a hearing system for adaptively matching microphones (3, 4) of a hearing system. The method comprising the steps of determining a true direction towards a sound source, determining an estimated direction towards the sound source using microphones (3, 4) of the hearing system, comparing the true direction with the estimated direction to obtain a correction factor, applying the correction factor to the signals of the microphones (3, 4) of the hearing system in order to reduce a difference between the true direction and a corrected estimated direction obtained via corrected microphone signals.
